I'm very excited to see that IBM has finally announced BLU, an architecture-aware compressed columnar engine in DB2. My old friends at Almaden Research worked super hard on this project, and were waiting until the product was released before they could brag about the stellar performance results that BLU achieved internally. I'm looking forward to seeing the BLU papers finally getting out to the research community. Here's Curt Monash's summary of the product announcement.
Here's a great video describing Blink from Guy @ Almaden.
